Hart River Region Stratigraphy and Mineral Exploration Targets

The Hart River area in the southeastern Ogilvie Mountains of Yukon is underlain by two widespread geological successions. This dataset from the Government of Yukon provides revised stratigraphy and identifies seven specific exploration targets for sediment-hosted base metal deposits. It was last updated on April 17, 2026.

Use Cases

• Identifying potential massive sulphide deposits based on associations with Hart River volcanic rocks.
• Mapping sedimentary copper deposit targets within the Fifteenmile Group stratigraphy.
• Evaluating 'Howard's Pass-type' zinc-lead deposit potential in unmapped Road River Group shales and chert.
• Assessing covered areas at the base of the Lower Schist for 'Macmillan Pass-type' zinc, lead, silver, barite deposits.
• Locating volcanogenic massive sulphide deposits associated with felsic volcanic rocks in the Keno Hill quartzite.

Strengths

• Identifies seven specific mineral exploration targets with deposit-type classifications.
• Covers two distinct geological sequences ('shelf' and 'offshelf') across a defined region.
• Published by the Government of Yukon, an authoritative geological source.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update date is in the future (2026).
